data of the binary systems
comprising 2-ethoxyethanol, 2-ethoxyethyl acetate, and toluene were
measured using an ebulliometer. The boiling temperatures of the binary
mixtures are reported for six different pressures ranging from 53.3
to 101.3 kPa. The binary system 2-ethoxyethanol–toluene shows
a low-boiling azeotrope around 90 mol % toluene. A nonrandom two-liquid
(NRTL) model was used to fit the binary (PTx) data.
The experimental data were verified using the thermodynamic consistency
tests of Redlich–Kister and Wisniak. The reported data were
compared with available literature data and modeling results. The
studied systems are relevant for the design of azeotropic/reactive
distillation columns for the esterification of 2-ethoxyethanol and
acetic acid using toluene as an entrainer.
